" i Specification of LettersPatent No. 2,734, dated July 20, 1842;

F0 czZZ'La/Lomzftmag/ concern.' j j Be itknownthat I, ELiseL-l` Barcos,of the town of Perry, in the county oflVyoming and `State of New York,have invented a new and useful Machine for rlfurning Fence`Picketsf'an'd all Articles of )Food ofa Uniform Cylindrical Form; andIdo hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the said machine,reference being had tothe annexed drawings, making a part of thisspecification, in whichf Figure 1, isa perspect-ive view of saidmachine; F ig. 2, afront view of the turning gouges, or chisels attachedto the anterior end of the revolving cylinder; and Fig. 3, alongitudinal section of the revolving cylinder. i

To enable others skilled inthe art, `to make and use my invention, Iwillproceed to describe its construction and operation.

I construct my machine as follows: I attach a bed plate of iron (a, Fig.l) to a block of corresponding width; into the iron bed plate, twelveiron standards, (c, c, c, c, f, f, f, j", z', z', z', z', Fig. 1,) arefirmly inserted; the bed plate lies horizontally, and the standards areinserted perpendicularly; the standards may be round or square; ifsquare, they must be inserted into the bed plate, diagonally; thestandards are placed in pairs, on opposite sides of the bedplate near`its outer edge; the two anterior pairs of standards, (c, c, c, c, Fig.1,) are placed near the front end of the bed plate, and support twofeeding rollers, (CZ, CZ, Fig. 1,) which rest on four bearing blocks; e,e, e, c, (Fig.

1;) the bearing blocks are fitted at each end to the correspondingstandards. The two central pairs of standards, (f, f, f, f, Fig. 1,)support the revolving hollow cylinder, g, (Fig. 1,) resting on twobearing blocks, (ZL, ZL, Fig. 1,) fitted to the standards. The twoposterior pairs ofstandards, (ZJ, i, z', Fig. 1,) are placed immediatelybehind the revolving cylinder, near the other end of the bed plate, andsupport two drawing rollers, (le, Zz, Fig. 1,) resting on( four bearingblocks, (Z, Z, Z, Fig. 1,) fitted to the standards. The bearing blocksof the upper feeding roller, slide up and down the standards, to allow alarger vor smaller stick, to pass between the feeding rollers, and arepressed down by a spring, (m, Fig. 1,) so as to apply the rollers firmlyto the stick passing beinashes into a perpetual screw, (g, l*

itween them. f The bearing blocks of the upper` drawing roller, slide upand down the standards, an-dlare fixed by screws and nuts, (a, a, a, a,Fig. 1,) on the top of the standards, so as to allow the stick to passbeltween the drawing rollers, after it has been irounded, by the gougesor chisels which are attached to the front end of the revolvingcylinder. One end of the shaft, (0, Fig. 1,) 3of the under feedingroller and also of the under 4drawing roller, passes through the bearingblocks, to a rest in a short upright standard. Between the lastmentioned standard, and the bearing blocks, on each lshaft, is a toothedpinion (p, Fig. 1,) which ig. l.) Between the pinio-ns, on the shaft ofthe perpetual screw, is a smalldrum, for turning the perpetual screw.,so as to give a rotary motion to thepfeeding and drawing rollers. The`revolving cylinder, (g, Fig. 1,) before mentioned, is made of castiron; through its center, from end to end, is a circular opening, (a,Figs. 2 and 3,) of the same size of the picketor stick after it has beenrounded. On the end of the cylinder, next to the drawing rollers, is ajournal, Fig. 3,) about half aninch in diameter, larger than thecircular opening. `blear the other end of the cylinder, another journal,(c, Fig. 3,) of the same size ofthe one before `d.escribed,is made by acylindrical depression in the cylinder.` On these journals, the cylinderrevolves, inthe two bearing blocks, between the two central pairsofstandards, allowing the anterior end of the cylinder, (r, Fig. l, ZFigs. 2 and 3) to project beyond the bearing block, on which itrevolves, toward the feeding rollers. On this projecting end of therevolving cylinder, four curved gouges or chisels, (s, s, Fig. l, and b,Z), b, b, Fig. 2,)

are' attached by wedges or keys, (t, t, Fig. 1, c, c, c, 0,Fig. 2,)fitted to depressions on the face of the end of the cylinder. Thecutting edges of the curved gouges or chisels vary in width, and areplaced around the circular opening of the cylinder, in such a manner,that the cutting edge of the widest gouge or chisel is most distant fromthe circular opening, and the others approach in regular gradation, tillthe edge of the narrowest gouge or chisel is on a line with the outsideof the opening. A revolving rest, (u, Fig. 1,) of the same shape andheight of the under feeding roller is placed on a line with the feedingrollers, so far distant from them, as to form a convenient rest forthe'stick to be turned. In the middle of the revolving rest, and in themiddle of each of the feeding and drawing rollers is a circulardepression, of such shape as to fit a square stick, when placeddiagonally between the feeding rollers.

The machine is placed upon a bench, over the drum from which it is toreceive the propelling power, and is put in operation by a belt or band,which passes from the propelling drum, over the revolving cylin- YYder,under Ythe. small drum on-the perpetual i screw, over a tighteningpulley, (fw, Fig. 1,)

down to, and over, the propelling drum. The size of the propelling drum,and the velocity of its motion should be such as to give to therevolving cylinder about two thousand revolutions per minute. Thepropelling power may be water, steam, or any other, suited to thepropulsion of machinery in general.

The operation of the machine is as follows: The cylinder being put inrapid revolution, a square stick of suitable size for the picket orother article desired, is placed Vupon the revolving rest, (u, Fig. 1,)and one end is then pushed between the feeding rollers, (d, cZ Fig. 1,)which immediately seize and carry it along to, and through, the

circular opening in the revolving cylinder, to the other end thereof,where it is grasped by the drawing rollers, and drawn completely throughthe cylinder. While the stick is thus passing it is rounded by thegouges or chisels on the anterior end of the cylinder. One end of thepicket is then pointed, if desired, by being placed in an opening in theend of a revolving spindle, to which a chisel is adapted, diagonally, soas to out the point of the shape desired. Any suit-able materials may beused in the construction of the machine, and the proportions may bevaried Yat pleasuresV Y The machine may be used for turning straight,round sticks, of any length, and of any size, not exceeding the diameterof the opening through the cylinder, forV any use or purpose.

What I claim as my invention, and wish to secure by Letters Patent, is-

The arrangement of machinery, by which a stick of any length, is carriedthrough, in combination with the revolving cylinder, with gouges orchisels on its anterior end, so arranged that the stick may be roundedwhile passing through the cylinder.
